چکیده

‎we pursue further our‎ ‎investigation‎, ‎begun in [h.~smith‎, ‎groups with all subgroups subnormal or‎ ‎nilpotent-by-{c}hernikov‎, ‎emph{rend‎. ‎sem‎. ‎mat‎. ‎univ‎. ‎padova}‎ ‎126 (2011)‎, ‎245--253] and continued in [g.~cutolo and h.~smith‎, ‎locally finite groups with all subgroups‎ ‎subnormal or nilpotent-by-{c}hernikov‎. ‎emph{centr‎. ‎eur‎. ‎j‎. ‎math.} (to appear)] ‎‎‎of groups $g$ in which all subgroups are either subnormal or‎ ‎nilpotent-by-chernikov‎. ‎denoting by $mathfrak{x}$ the class of all such‎ ‎groups‎, ‎our concern here is with locally finite p-groups in the class‎ ‎$mathfrak{x}$‎, ‎where $p$ is a prime‎, ‎while an earlier article provided a‎ ‎reasonable classification of locally finite $mathfrak{x}$nb-groups in which‎ ‎all of the p-sections are nilpotent-by-chernikov‎. ‎our main result is that‎ ‎if $g$ is a baer p-group in $mathfrak{x}$ then $g$ is nilpotent-by-chernikov‎ .

Locally soluble-by-finite groups with small deviation for non-subnormal subgroups

A group G has subnormal deviation at most 1 if, for every descending chain H0 > H1 > . . . of non-subnormal subgroups of G, for all but finitely many i there is no infinite descending chain of non-subnormal subgroups of G that contain Hi+1 and are contained in Hi. This property P, say, was investigated in a previous paper by the authors, where soluble groups with P and locally nilpotent groups ...

Finite Groups Whose «-maximal Subgroups Are Subnormal

Introduction. Dedekind has determined all groups whose subgroups are all normal (see, e.g., [5, Theorem 12.5.4]). Partially generalizing this, Wielandt showed that a finite group is nilpotent, if and only if all its subgroups are subnormal, and also if and only if all maximal subgroups are normal [5, Corollary 10.3.1, 10.3.4]. Huppert [7, Sätze 23, 24] has shown that if all 2nd-maximal subgroup...

Subgroups defining automorphisms in locally nilpotent groups

We investigate some situation in which automorphisms of a groupG are uniquely determined by their restrictions to a proper subgroup H . Much of the paper is devoted to studying under which additional hypotheses this property forces G to be nilpotent if H is. As an application we prove that certain countably infinite locally nilpotent groups have uncountably many (outer) automorphisms.

The Nilpotency of Some Groups with All Subgroups Subnormal

Let G be a group with all subgroups subnormal. A normal subgroup N of G is said to be G-minimax if it has a finite G-invariant series whose factors are abelian and satisfy either max-G or minG. It is proved that if the normal closure of every element of G is G-minimax then G is nilpotent and the normal closure of every element is minimax. Further results of this type are also obtained.
